(01. 33- 180 p, This invention relates to gauges and comprises members 'i-nthe form of roller segments I 8 which all of the features of novelty herein disclosed. are adaptedtoengag'e the edges of'the openings An object of the invention is to provide a gauge in the same manner as the bearing rollers. That for testing the form and/or location of a series is, the segments will partially enter the openings of openings in a ring. Anotherobject is to probut, like the bearing rollers, are too large to pass 5 vide a machine for accurately indicating when entirelythrough theopenings. Each segment is a bearing separator or cage has its "rolling ele-" secured by aheaded screw 20 countersunk therement receiving openings properly formed for efin and threaded into a slide 24 which has a conficient co-operation with rolling elements.

The illustrated cage support the cage. 1 comprises a body portion H) which is conical and Before the cage is applied, the slides are urged provided with openings l2 for the rollers, these inwardly by coiled tension springs 54 each anopenings conforming to the transversecurvature chored to a screw 5.6 on the Iblock 32 and to a 45. of the rollers but not being large enough to alpin' '58 projecting downwardly from the slide low the rollers to pass through'the openings from through a slot '60. The spring is contained in a the inside. The cage also has an end flange l4 hole of the block 32 and this hole is closed at its and a plurality of fingers 16 which are subseouter end bya screw plug 162. I quently bent inwardly substantially parallel to 'The'bIock has a portion centered in an opening 50: the body portion to hold the rollers in their 64 of a hollow base 366 having-an upwardly pro- 5 openings. The present 'cage-is adapted for bar jecting rim 68 which is tapped at intervals to rerel shaped rollers R which have fiat ends and a.- ceive clamping screws 10 projecting into-an ansurface which is curved on an arc. nular groove of the block. To furnish :a uniform The form and location of the openings 1 :are pressure tending to raise the cam 28 and so 55. tested by shoving into a plurality of them gauge thrust all "of the slides outwardly, a coilspring 12 is anchored by a screw plug 14 in the block 32 and connected at its lower end to a crank arm 16 having its end forked to straddle flat sides'l8 at the lower end of the shaft 30, each arm of the fork also being forked to straddle a pin 80 which is passed through the shaft.

The crank arm I6 is secured by set screws 82 to a shaft 84 which is rockably mounted in bearing lugs 86 on the base, a "crank handle 88 being pinned to the shaft outside of thebase for manual operation when the cam is depressed to apply the cage to operative position. The shaft 84 is held from endwise movement by the hub of the crank Y handle and by a collar 90 pinned to the opposite end of the shaft. I

In order to obtain an indication of the amount of upward movement of the shaft 30 which indi-* cation gives an average of the extent of projec-g.

tion of the three gauge segments into the cage pin 94 and bears at its end against the lower end of a gauge stem 96. The .stem'is slidable in a. hollow post 98 carrying an indicator, I00, the post being held in a hollow boss l-ll2 on the frame, the boss being split and clamped around the post by a clamp screw I04.

Dust is excluded from the interior of the hollow base by a dust plate. lQBfastened byscrews I08. The base is adaptedto be fastened to any. suitable bench or table, and for this purpose has a number of outwardly extending, feet or lugs H8 which are apertured for fastening devices.

In a modification illustrated in Figure 11 and adapted for smaller cages, gauge segments I8A to fit the corresponding roller openings are secured to radial slides 24A which are urged inwardly by compression springs 54A abutting against a washer backed up by a pin su ra. jecting from the slide, the outer ends of the springs abutting against a screw, plug" 62A threaded in the block 32A. 1

In operation, the handle 88 is turned to lower. the cam 28, the small'coil springs 54 thereby urging the slides 2.4 radially inwards. A separator, cage or similar ring is thenlaid on the support provided by the block and its cover. The handle is then released, the large coil spring 12, thereupon lifting the cam 28 which forces the slides outwardly. The gauge members or'segments l8 which, like the bearing rollers, are 'too large to pass through the openings, engage the rims of the openings [2 with a definite pressure which is independent of the human element, this pressure being equalized because the article floats or be comes supported by the three gauge members clear of the support. The extent of fupward movement of the cam is shown by the indicator I and this movement'provides an indication" of the average extent of entry ofthe gauge members into the openings. This reading is com pared with that previously obtained by measurements on a master articlehavingits openings properly spaced and contoured. Articles which are not of the right diameter or 'do not have the openings properly shaped within prescribed limits are rejected. In the case of bearingseparators. or cages, some uneven spacing of the openingsis permissible and the -dive rging;guide slotsf34';

will permit two of the gauge members to have a slight circumferential movement; to align with;

their openings. 1
